Comprehensive understanding of groundwater - surface water (GW–SW) interaction is essential for effective water resources management. Groundwater (GW) and surface water (SW) are closely connected components that are constantly interact each other within the Earth’s hydrologic cycle. Many studies utilized observations to explain the GW-SW interactions by carefully analyzing the behavior of surface water (SW) features (streams, lakes, reser voirs, wetlands, and estuaries) andthe related aquifer environments. Surface water bodies gain water and solutes from groundwater systems, and in other cases surface water bodies recharge groundwater, which causes changes in groundwater quality. The interfaces between GW and SW environments, such as hyporheic - benthic zones and riparian corridors often function as biogeochemical hotspots and can have significant influences on the entire stream ecology. However, unlike visible surface water, groundwater, an invisible water resource, is not easy to measure or quantify directly. Nevertheless, demand for groundwater that is highly resilient to climate change is growing rapidly. Furthermore, groundwater is the prime source for drinking water supply and irrigation, hence critical to global food security. Groundwater needs to be managed wisely, protected,and especially sustainably used. However, this task has become a challenge to many hydrologic systems in arid to even humid regions because of added stress caused by changing environment, climate, land use, population growth, etc. In this issue, the editors invite contributions on various research areas such as the integrated GW-SW analysis, sustainable management of groundwater, and the interaction between GW and SW. Methodologies, strategies, case studies as well as quantitative techniques for dealing with combined surface water and groundwater management are of interest for this issue. Studies describing how groundwater resources benefit from an Integrated Water Resources Management (IWRM) approach are welcome. This special issue aims to elevate integrated understanding of the science in GW-SW system through healthy discussions in the GW-SW system researc h community. The editors also welcome contributions from all relevant areas that improves every aspectof GW-SW connections and its beneficial use.

Title: A new physically-based, spatially-distributed groundwater flow module for SWAT+
Affiliation: Colorado State University
Abstract: Watershed models are used worldwide to assist with water and nutrient management under conditions of changing climate, land use, and population. Of these models, SWAT and SWAT+ are the most widely used, although their performance in groundwater-driven watersheds can sometimes be poor due to a simplistic representation of groundwater processes. In this paper we present a new physically-based, spatially-distributed groundwater flow module called gwflow for the SWAT+ watershed model. The module is imbedded in the SWAT+ modeling code and is intended to replace the current SWAT+ aquifer module for watersheds with strong stream-aquifer connections. The model accounts for recharge from SWAT+ HRUs, lateral flow within the aquifer, ET from shallow groundwater, pumping, groundwater-surface water interactions through the streambed, and saturation excess flow. Daily groundwater head and groundwater storage is solved using an explicit numerical method approach for the groundwater balance equation, with head and flow values for the current day based on head and flow values from the previous day. The modified SWAT+ model is applied to the Little River Watershed (327 km2) in southern Georgia, USA, demonstrating its capabilities of simulating land both surface and subsurface hydrological processes. The inclusion of the gwflow module increases run-time by 20% compared to the original SWAT+ modeling code. Using the modified SWAT+ model can provide physically realistic groundwater flow gradients, flux values, and interactions with streams for modeling studies that assess water supply and conservation practices.
